Test: Alternator vs. no alternator = 10% MPG gain @ 70 km/h

IF you really need POWER Generator

I suggest Thermoelectric generator..

it turns IR(heat) into power...


Think outside the box


a 45Watt version will be almost $800... you could hook it upto the output of the exhaust...300C will give you about 45watts of power

That has also been discussed before. The problem with thermodynamic generators is the cooling side. You simply need an enormous cooling fin.
On top of that TEGs are very expensive for the power they produce, so only make sense in applications that run continuously. Most cars are used less than 10% of the time.

People always say peltiers are too fragile.

Since the early-2000s, nearly every major automaker and exhaust supplier has experimented or studied thermoelectric generators, and companies including General Motors, BMW, Daimler, Ford, Renault, Honda, Toyota, Hyundai, Valeo, Boysen, Faurecia, Tenneco, Denso, Gentherm Inc., Alphabet Energy, and numerous others have built and tested prototypes.

My 2017 Civic does it too, nice feature to have.

Hand/peddle crank generator :P

make your passenger do it LOL

Or solar panel and big capacitor bank??


Also another option is use alternator that that has alternator field disconnect.

I prefer lassoing a semi, but when someone cuts you off you are going to have a bad day.

i'm in a big SUV,

I read that sport-utility vehicles are more likely to be in fatal accidents.

Fatal to the people in the other car.

100% true I saw a 1996 tahoe right into a 1990s Honda wagon accord it ripped the accord apart( the driver side door was compressed to the passenger side) and the passengers got ejected.. mind you the Tahoe was going 55mph (speed limit) and the accord made an unsafe u turn in front of the accord.. the guy in the tahoe walked away..

same
it also happened again last year as well another car made an unsafe turn they got double t-boned on both side of the car (a truck and car hit it in both directions at the same time)


lets just say the car went from 6 feet wide to 2 feet wide
